Application filed December 22, 1887. Serial No. 258,668. (No model.)Patented in England October 24, 1883, No. 5,059.

.To all whom it may concern.-

Be it known that I, VILLIAM HURST, of Rochdale, in the county ofLancaster, England, (COlJtOH'SPlDI'lGIQ) have invented a new and use fulImprovement in Machines for Linking WVarps, (for which I have obtainedLetters Patent of the United Kingdom of Great Britain and Ireland, No.5,059, dated October 241383,) of which the following is a specification.

My invention relates to machinery or apparatus for forming what arecommonly called chained or linkedHvarps. By means ofmy lnvention I amenabled to chain or link warps more quickly and with greater certaintyand regularity than heretofore, and by my invention the yarn beinglinked or chained is sub jected to less strain and injury than it hashitherto been while being chained or linked by machines hitherto in use.

My invention consists in the mechanism hereinafter described and claimedfor effecting the chaining and linking operations.

In the accompanying drawings, Figure 1 is a side elevation of a machineconstructed according to my invention. Fig. 2 is asectional plan of thesame; Fig. 3, a partial front view; Fig. 4, a plan upon a larger scale;and Fig. 5 a front view, also upon a larger scale. Figs. 6, 7, 8, and 9are views showing portions detached, and Figs. 10, 11, 12, 13, 14, 15,and 16 illustrate the formation of the chains or links. Fig. 17 is afront view, and Fig. 18 a side view representing a modified mechanismfor actuating the trumpet through which the warp to be chained or linkedis passed. Fig. 19 is a diagram representing an apparatus by means ofwhich the threads forming the chained or linked warp are drawn directfrom the bobbins.

The same letters of reference are applied to corresponding partsthroughout the whole serles of figures.

In the accompanying drawings, a (0* are end frames connected at the topby a cross-frame or cross-beam, b. Extending between the end frames, a(5, and secured thereto, is a crossframe or cross-beam, 0.

(Z is a shaft supported in bearings, secured to the end frames, a arespectively. Upon the shaft (Z are a fast pulley, e, and a loosepulley, f. The shaft (Z is provided with collars, by which such shaft (Zis prevented from moving longitudinally. Fast upon one end of the shaftd is a bevelwvheel, g, gearing into a bevel-whee], h, fast upon avertical shaft, j. The vertical shaftj is supported in bearings 70. Fastupon the lower end of the vertical shaft 3' is a plate, Z, to which issecured a crank-pin,

on. The shaftj is prevented from movinglongitudinally by means of theboss of the bevelwheel h and the boss of the plate Z. Fast upon theshaft d are bevel-wheels an The bevelwheel a gears into a bevel-wheel,0, fast upon a vertical shaft, 19, carried by a bracket secured to thecross-frame or cross beam 0.

Fast upon the lower end of the shaft 1) is a plate, q, provided with acrank-pin, r. The shaft p is prevented from moving longitudinally bymeans of the boss of the wheel 0 and the boss of the plate q. Thebevel-wheel a" gears into a bevel-wheel, 0*, fast upon a vertical shaft,11*, carried by a bracket secured to the cross-frame or cross-bcan1 0.

Fast upon the shaft 19* is a plate, q provided with acrank-pin, 0*. Theshaft p is prevented from moving longitudinally by the bosses of thewheel 0* and of the plate Projecting from the cross-frame or crossbeam cis a bracket, 8, supporting a vertical shaft, t. Fast upon the upper endof the shaft 15 is an arm, n, to which is j ointed an arm, 2;, providedwith a trumpet, w. The arm n. is formed with a slot, n, in which the armn is capable of being moved vertically upward and downward. Upon thelower end of the shaft 75, and fast therewith, is an arm, 00, providedwith a pin, 00, embraced by one end of a connecting-rod, y, the otherend of which embraces the crankpin m, carried by the plate Z.

Secured upon the shaft d is a cam, z, which, as the shaft (Z rotates,causes the arm :1; to be raised and lowered while the said arm v isbeing moved lengthwise of the cam e, as will be hereinafter moreparticularly described.

As some of the parts to be hereinafter described are repeated upon bothsides of the machine, I shall describe such of the said parts as aresituate at one side of the machine and affix to corresponding partssituate at the other side of the machine the same letters ofreference,with the addition of an asterisk, thus Secured to thecross-frame or crossbeam c is a bracket, Z, (shown more clearly in thedetached views,Figs. 6, 7, 8, and 9,) Fig. 6 being a side view; Fig. 7,a side view, partly in section; Fig. 8, a crosssection taken on the lineA B of Fig. 7, and Fig. 9 a view showing a portion detached. The bracketZ is provided with a recess, 2, formed therein, and along a portion ofthe upper edge thereof are formed ledges which support a bar, 3, capableof being slid longitudinally upon the said ledges. The end of the bar 3is extended, as indicated by the dotted lines in Fig. 2, and curvedsidewise at its extremity, so as to form a hook, 4, such bar 3,with itshook 4,being more clearly shown in the detached View, Fig. 9. 5 is aplate secured to the cross-frame or cross-beam c by screws, a projectingpart of which plate 5 is curved at its extremity, so as to form a hook,6, and an extended part of a bracket, 7, is also curved sidewise at itsextremity, so as to form a hook, 8. The end of the hook 6 is curveddownward, and the end of the hook S is curved upward, the said two endsbeing in contact and forming a hollow hook, 9, which, for convenience, Iwill hereinafter refer to as the book 9. Within such hollow hook 9 theextended end of the bar 3 is capable of being slid backward and forward,as will be hereinafter pointed out. To a part of the bar 3 is attachedone end of a spring, 10, the other end of which is secured to aprojecting part of the cross-frame or cross-beam 0. The spring 10 tendsconstantly to draw the bar 3 in the direction indicated by the arrow 0.Secured to the bar 3 is a bracket, 11, part of which is situate withinthe path of a revolving cam, 12, so as to be capable of being movedthereby in a direction opposite to that indicated by the arrow 0, themovement of the bar 3in the directiou indicated by the arrow 0 beinglimited by a stop, 13, on the bar 3, and a stop, 14, secured to thecross-frame or cross'beam c. The cam 12 is mounted fast upon the shaftd,

Secured to the end frame, a, is a bracket, 15, to which a stud, 16, issecured. Mounted upon the stud 16, so as to be capable of being rotatedthereon, is a wheel, 17, the teeth of which gear into the teeth of arack, 18, provided with projecting parts, which are embraced by abracket, 19, secured to the bracket 15, in which bracket 19 the rack 18is capable of being slid longitudinally while its teeth are in gear withthose of the wheel 17. The teeth of the wheel 17 and the teeth of therack 18 are indicated by dotted lines. To one end of the rack 18 aconnecting-rod, 20, is connected by means of a pin, 21, the other end ofthe connecting-rod 2O embracing the crank-pin r, secured to the plate q.Fast with the wheel 17 is an arm, 22, provided with a curved part, whichconstitutes a hook, 23. Upon rotary motion being imparted to the pulleye, so that such pulley e rotates in the direction indicated by the arrowD, the plate Z and crank-pin at will be rotated in the directionindicated by the arrow E. The rotation of the crank-pin at will, bymeans of the connecting-rod y, pin an, arm :0, shaft t, arm a, and arm'0, cause the .and then in the other.

trumpet w to be oscillated sidewise. The cam 2 being rotated in thedirection indicated by the arrow D, the rotation of such cam 2 willcause the arm '0 and trumpet w to be raised and lowered twice duringeach revolution of the cam z. The rotation of the plate Z will cause thetrumpet w to be oscillated sidewise to the points F and alternately, andwhile the trumpet w is being so oscillated the cam 2 will cause suchtrumpet w to be carried along the line G (1* in the direction indicatedby the arrows H, the said trumpet w first passing below and around thehook 9 and then be low and around the hook 9*. Upon rotary motion beingimparted to the plate (1, so that such plate q is rotated in thedirection indicated by the arrow K, the rack 18 will, by means of theconnecting-rod 20, be caused to traverse longitudinally first in onedirection The traversing of the rack 18 will, by means of the wheel 17,cause the hook 23 to be turned first in one direction and then in theother, the said hook 23 at certain times passing between the hook 6 andbracket 7 and beneath the hook 4. To feed the warp to be chained orlinked to the chaining or linking machine at such rate that little or notension is produced upon the warp while such warp is being chained orlinked, I employ the apparatus to be next described.

24 24* are end frames, to which are respectively secured brackets 2525*, supporting a shaft, 26, fast upon which is mounted a drum orroller, 27. The shaft 26 is prevented from moving longitudinally bycollars formed thereon or seen red thereto. Resting upon the drum orroller 27 is a roller, 28, having an axle, 29, which axle 29 issupported by brackets 30 30*, in which it may be rotated. The brackets30 30* are respectively secured to levers 31 31*, one end of each ofwhich turns upon a bar, 32. the ends of which pass into openings formedthrough the end frames, 24 24*. Depending from the ends of the levers 3131* are weights 33 33*, respectively, such weights 33 pressing theroller 28 into contact with the roller or drum 27.

34 is a shaft, one end of which shaft 34 revolves in a bracket securedto the end frame, 24*, while the other end of such shaft 34 is capableof being rotated in a bracket carried by a lever, 35. The lever 35 iscapable of being turned at one end upon a stud secured to the end frame,24. The shaft 34 is prevented from moving longitudinally by means ofcollars.

36 is a shaft passing through and capable of being revolved in holesformed through the end frames, 24 24*. Upon the shaft 36 is secured a'cam, 37, which is situate beneath the lever 35. Fast upon the shaft 36is an arm, 38, provided with a stud which passes into a hole formedthrough the end of a rod, 39, by means of which the machine may bestarted or stopped. Fast upon the shaft 34 is a pulley, 40, around whichpasses an endless belt, 41, which communicates rotary motion to thepulley 40 from any convenient source of power.

Fast upon the shaft 34 is a pulley, 42, the circumference of which ispreferably covered with leather. The pulley 42 is shown as being incontact with a pulley, 43, fast upon the shaft 26. Fast upon the shaft26 is a pulley, 44, around which and around the pulley 6 passes anendless crossed belt, 45, such belt 45 transmitting motion from thepulley 44 to the pulley e and shaft (1. Secured to the bar 32 is an eye,46.

Having thus described the various parts of the machine, I will proceedto show in what manner they operate when forming a warp into a chain orlinks.

The warp L to be chained or linked is passed through the eye 46 andbetween the drum or roller 27 and roller 28, after which such warp L ispassed through the trumpet w and around one of the hooks 9 9*. Duringthis time the rod 39 has been raised, so as to allow the pulley 42 topass out of contact with the pulley 43. Upon the rod 39 being lowere-dthe pulley 42 will be pressed against the pulley 43 and the drum orroller 27 and roller 28 will draw forward the warp L and deliver it tothe trumpet w. Icause the drum or roller 27 and roller 28 to rotate atsuch circumferential speed that the warp L is delivered to the chainingor linking apparatus at such speed that little or no tension is producedin the warp Lwhile such warpL is being chained or linked. The diagrams,Figs. 10 to 16, inclusive, show the manner in which the partshereinbefore described operate in order to form the warp L into a chain.

In Fig. 10 the trumpet'w has passed'beneath and around the hook 9*,leaving the warp L passed around such hook 9*, and by a continuedmovement has passed beneath and around the hook 9, and again beneath andaround the hook 9*, until it arrives in the position in which it isindicated in Fig. 10. The hook 23*, turning in the direction indicatedby the arrow M*, as will be hereinafter de scribed, brings forward aloop, N*, of warp previously passed around the hook 9*. A continuedmovement of the hook 23* in the direction indicated by the arrow M* willcarry the loop N* of warp clear of the hook 9* and allow the said loopN* of warp to pass upon the loop 0* of warp, which is around the book9*, as shown in Fig. 12. The sliding hook 4* is then drawn in thedirection indicated by the arrow 1 by the rotation of the cam 12*, anddraws along with it the loop 0* of warp until it arrives in the positionin which it is indicated in Fig. 13, and while the sliding hook 4* isinsuch position the revolving hook 23* passes in the direction indicatedby the arrow Q*, beneath the hook 4*, and through the hook 9*, afterwhich the hook 23* is rotated in the direction indicated by the arrowM*, after which the sliding hook 4* will be liberated by the rotation ofthe cam 12* and be drawn by the spring 10* into the position in which itis indicated in Fig. 14. A loop, R*, of warp is then passed around thehook 9* by the trumpet w, and a repeated movement of the hook 23* in thedirection indicated by the arrow M* will carry the loop 0* of warp clearof the hook 9* and be about to pass it upon the loop R and the partswill arrive in the positions in which they are indicated in Fig. 15,when the cycle of motions for forming one link of the chain will havebeen completed.

I have confined my description to forming the chain at one side only ofthe machine, and the motion and action of the parts at the op positeside of the machine being similar to and alternate with those abovedescribed, a further description thereof will be unneces' sary. Aportion of warp, chained or linked, as above described, is shown by Fig.16, which is a diagram of a portion of warp when chained or linked. Thewarp to be chained or linked by the machine above described may beformed upon a warping-mill or beamingmachine, by which threads areusually formed into a warp.

Another method of actuating the trumpet w is shown by Figs. 17 and 18,Fig. 17 being a front view and Fig. 18 a side view. To parts which aresimilar to parts previously re ferred to I shall afiix the same lettersof reference as I have affixed to similar parts above mentioned.

j is a vertical shaft, which imparts rotary motion to the shaft 47 bymeans of the bevelwheels 48 49. Fast upon the shaft47 is a bevelwheel,50, which gears into another bevelwheel, 51, fast upon a shaft, 52,mounted and capable of being rotated in brackets secured to thecross-frame or cross-beam 53. Fast upon the shaft 52 is a cam, 54. Tothe crossframe53aresecured \I-guides 55, within which and capable ofbeing slid therein is a plate, 56. Upon the plate 56 is mounted a stud,upon which is mounted a bowl or roller, 56.

Secured to the plate 56 is a stud, 57, from which depends a rod, 58, thelower end of which is connected by the universal joint 59 to the arm n,jointed to the arm a fast upon the shaft i. To the arm 7; is secured thetrumpet w. The rotation of the cam 54 will cause the arm 1) and thetrumpet w to be raised and lowered in a manner similarto that previouslydescribed.

In some cases I propose to form a chained or linked warp by means of theabove-described ehaining or linking apparatus or ma chine by taking theyarns or threads from which the warp is to be formed direct from thebobbins upon which such yarn or thread has been spun or wound. For thispurpose I pass the threads or yarns between or around rollers,which, bymeans of their revolving surfaces, draw off the yarns or threads fromthe bobbins aforesaid, and deliver the said yarns or threads to thelinking or chaining apparatus or machine. The yarns or threadsaforesaid, in their passage from the bobbins previously mentioned to thechaining or linking machine or apparatus, pass through a heck or similarapparatus for arranging the yarns or threads in an order suitable forweaving. After the warp has been chained or linked by the machine orapparatus above described, it may either all upon the floor or othersurface beneath the chaining or linking machine or apparatus to besubsequently removed, or the said warp may be passed over suitablepulleys or guides to be conveyed thereby to any convenient place. Thesaid pulleys may have rotary motion imparted thereto, if desired. Thisarrangement of apparatus is shown by Fig. 19. Ais the creel, in whichare placed the bobbins containing the yarns from which the warp is to bemade. B is aheck, and O C are rollers or rods, such as are ordinarilyemployed for taking up the slack yarn or thread in beaming machines. Theyarns or threads are passed through the heck B, then overand under therollers or rods 0 to the rollers E E, and thence to the trumpet w ofthechaining or linking machine.
